#92600 - 2003-08-11 06:56 PM Checking to see if File Is In Use
Lee Wilmott Lee Wilmott Starting to like KiXtart Registered: 2002-09-17 Posts: 106 Loc: Bristol, UK	I hope someone can help me...This topic may have come up before, but when I did a search I couldn't find anything... Anyway...I would like to check to see if a particular file is in use. I CANNOT try and open the file for Read/Write access and test whether the return code is not zero. Ideally I would like to search the list found in Computer Management (Windows 2000)..."System Tools\Shared Folders\Open Files" and look for a particular entry. Is it possible to search this list? Cheers guys, Lee

Here is my code... code: Dim $strFileName, $strComputer Dim $objWMIService, $colFiles, $objFile CLS $strFileName = "e:\\apakds\\apak\\sas\\action.ldb" $strComputer = "." $objWMIService = GetObject("winmgmts:" + "{impersonationLevel=impersonate}!\\" + $strComputer + "\root\cimv2") $colFiles = $objWMIService.ExecQuery ("SELECT * FROM CIM_DataFile WHERE Name = '" + $strFileName + "'") For Each $objFile in $colFiles ? "Name: " + $objFile.Name ? "File name: " + $objFile.FileName ? "InUseCount: '" + $objFile.InUseCount + "'" Next If I look in Computer Management (Windows 2000)..."System Tools\Shared Folders\Open Files" I can see that this particular file has "4" locks. However, when I run this code it returns the following... code: InUseCount: '' Why doesn't it return "4". I would have expected a numerical value to be returned. Can anyone help me? Lee

I've ran that against my own computer and a fileserver, filtering for any file where InUseCount<>NULL and didn't get a single return. Teh MSDN documentation is pretty poor and I haven't been able to find a single script that actually uses that property, they normally just display it. [ 12.

Kdyer Kdyer KiX Supporter Registered: 2001-01-03 Posts: 6241 Loc: Tigard, OR	Not sure if this helps.. But here is some code that uses this property - http://www.scriptinternals.de/content/ref/wmi/namespaces/root_cimv2/CIM_DataFile/InUseCount.htm If you can get around the German.

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11164 Loc: Boston, MA, USA	I do get around the German. It actually one of the scripts i found when investigating it this morning. Note, that it not really uses the property, it only displays it. I do not get around the fact that InUseCount returns NULL for everything. _________________________ There are two types of vessels, submarines and targets.

I believe it will return "" if the file is in use. code: if getfiletime($file) = "" ;file in use else ;file not in use endif _________________________ Eric
